I would beg to differ on your comment that "Once the concrete is set, there is very little, if any, water absorption". I have water wicking through the concrete floor in my basement quite regularly. Having seen the salts that are washed out of the concrete by water wicking through tells me that concrete really does absorb (or pass) water. The only way to stop that is to seal it somehow.
Well, maybe so, but what this tells me is that you should have found a better contractor. And if there really is salt leaching out of the concrete, then you have a major structural problem, since your rebar will be completely rusted out by now. This is not a very unusual problem, since shady contractors can save a few buck by using beach sand for the concrete mix.
I seem to recall a building collapsing recently in Mexico because of cheap beach sand.
